SPECIFICATION forming part of Letters Patent No. 569,507, dated October13, 1896.

Application filed March 12,1896. Serial NO 582,943. (NO model.)

To all whom it may concern.-

Be it known that I, J OSEPH J. MILNE, a citizen of the United States ofAmerica, residing at Monmouth, in the county of Varren and State ofIllinois, have invented certain new and useful Improvements inStump-Extractors; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

This invention relates to improvements in stump-extractors of that classwhich are operated by horse-power; and it comprises a drum supported ina suitable frame and adapted to be rotated by a sweep carrying a brackethaving an annular bearingsurface which bears upon the supporting-frame,said sweep also carrying two levers, which are connected to independentpawls, one of said pawls being adapted to throw the sweep in engagementwith the drum and the other engaging ratchetteeth in the lower end ofsaid drum to prevent backward rotation thereof, the connecting-rod ofthe latter pawl carrying a conical block which bears in a correspondingrecess in the drum to act as a brake upon the same when said pawl isthrown out of engagement with the ratchet-teeth.

The invention consists in the construction and combination of the parts,as will be hereinafter fully set forth, and particularly pointed out inthe claims.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective view of a stump-extractor constructed in accordancewith my invention. Fig. 2 is a vertical sectional view, and Figs. 3, I,and 5 are detail views.

A A designate runners upon which the supporting-frame of the machine ismounted, said supporting-frame consisting of a base-plate A, secured atits ends to the runners A and provided with three or more standards oruprights a a" a, upon which the upper plate A of the supporting-framerests and is secured thereto. The standards or uprights are pr'eferablyhollow, so that the bolts a which connect the upper plate of the framethereto, pass through said standards and receive nuts at their upperends, which are screwed down upon the plate to form a rigid frame. Thestandard a, which is located at the forward end of the frame, isprovided with a reinforc ing-web, as shown, and to this standard thedraft mechanism is attached.

l3 designates the drum which is placed between the plates A and A beforethe plate A is bolted in position, and this drum is provided at itslower end with a hub b, having an axial recess forming a continuation ofa vertical recess through the drum. The hub b is provided with anannular bearing-surface I), adjoining the head of the drum which bearsupon the base-plate A, the hub passing through an opening in saidbase-plate. The lower head of the drum B is provided near its outeredge, and on the under side thereof, with ratchet-teeth with which apawl, hereinafter described, engages, and the outer end of the hub 11 isbeveled inward, as shown, to provide a bearing-surface for the brakemechanism. The upper head of the drum B has formed thereon a hub b whichpasses through an opening therefor in the upper plate A of the frame,and the end of this hub has a series of ratchet-teeth or projectionsforming transverse recesses with which a verticallysliding bar or pawl6, carried by a bracket 0, secured to the sweep O, is adapted to engageto throw said sweep in engagement with the drum.

The bracket 0 consists of a flanged plate, to which the sweep is rigidlysecured, and

depending from this flanged plate is a cylindrical casing or housing,which lies over the hub of the drum B and presents an annular surface,which bears upon the upper plate A of the supporting-frame, the lowerend of said casing or housing having an outwardlyprojecting flange overwhich lie two segmental plates (1 and (1, attached to the plate A andadapted to retain the bracket 0 and sweep carried thereby in connectionwith the supporting-frame. The depending casing or housing of thebracket 0. is provided with vertical slots or recesses c 0, located dia-IOO metrically opposite each other, and within these slots the ends ofthe vertically-moving cross-bar or pawl e bear, said cross-bar or pawlbeing connected to a rod 2, which extends up through an opening in thebracket C and sweep O and is connected at its upper end to anoperating-lever E. The lever E is fulcrumed or pivoted to a segment-rackf, projecting from a base-plate F, which is secured in place upon theupper side of the sweep G, and the lever is provided with the usualsliding dog, which engages the teeth of the segment-rack to hold saidlever in an adjusted position. The lever E is operated to move thecross-bar or pawl e in and out of engagement with the ratchet-teeth atthe upper end of the hub 5 and when in engagement with saidratchet-teeth the movement of the sweep in the pro'perdirection willrotate the drum B, while an-opposite movement of the sweep would causesaid cross-bar or pawl to ride over the inclined surfaces o'f'the teeth,the pawl being allowed to slide upon the connecting-rod e and is forceddown by a helical spring e which encircles said connecting-rod and isinterposed between a shoulder thereon and the plate F.

The under side of the base-plate A is provided with depending 'flangesproviding a pocket in which is located a pawl-G, whichis pivoted thereinby a pin g, the end of the pawl adjoining thepivot havinga projectionwhich passes through an opening in the-baseplate A andengages theratchet-teeth b on the lower head-of the drum, the other end of saidpawl projecting across the hub 19 of the drum v-here it is engaged byahelicalspring g, interposed between the pawl and baseplate. The spring gacts to'throw the opposite end of the pawlGi-n engagement with theratchet-teeth b these teeth being pitched with respect to the teeth atthe upper-end of said drum, so as to prevent backward rotation ofthelatter. Through the pawl-G passes a rod h, the lower end of which isprovided witha nut or head 77., which bears upon the under side of thepawl, and this rod eritends upwardly through the drum B, bracket 0', andsweep O, the upper end thereof being connected by an adjustable nut to asecond operating-lever H, .pi voted to a segment-rack f, projecting fromthe plate F and provided with a sliding dog adapted to hold said leverin an adjusted position.

Upon the lower end of the connecting-rod h, above the pawl G, is mounteda conical block I, which is adapted to be brought in contact with thecorresponding surface at the lower end of the hub-Z) when the lever isoperated to draw upon the rod 72 It will be here noted that whentheconnecting-rod h isdrawn upon the operation first throws the pawl-Gout=of engagement with the ratchetteeth 11 and then moves the conicalblock in engagement with the hub-1), so that it will act as a brake uponthe drum.

A seat K is mounted upon the sweep O in position so that theoperating-levers E and H will be within easy reach thereof.

The body of the drum B may be cast in a single piece; but I prefer toconstruct the same as shown in the accompanying drawings, in which thecore is cast integral with the heads and is constructed to provide anumber of fiat surfaces adapted to receive a wood covering. At one endof each fiat surface the adjoining head of the drum is provided with arecess or seat b adapted to receive the reduced end of a wooden blockthe otherend of said block beingalso reduced to fit between lugs b,which project from the opposite head of the drum. The block is furtherheld in place by a screw which passes through the same into the core, orthe screw may be passed through one of the heads of the drum into theend of the block. Bythis arrangement the body of the drum is made up ofa series of wooden blocks secured in place around the core, and whenthese blocks are worn they can be readily removed and new onessubstituted. "One of the blocks is provided'with the usual meansfor-connecting the rope to the drum-and for guidingthesec- 0nd bite ofsaid rope.

From the foregoing description the operation of the machine will bereadily understood, as when the sweep is turned bya-horse or other powerand the pawls e'and G are in en gagement with their ratchet-teeth'thedrum will be rotated to wind the rope thereon, and when it is desired tocheck the rotation of the (h'um it is only necessary tooperate the leverE to move the cross-bar or pawle out of engagement with theratchet-teeth at .the upper end of said drum. In unwindingithe ropeorpaying it out from the-drum the lever-H is operated, which disengagesthe pawl G and operates the brake-block I, as hereinbefore described.
